At the 1 hour 16 stage, i have come across an error when i try to enter the chat message:
GET http://localhost:5000/socket.io/?EIO=3&transport=polling&t=MvziWt_ net::ERR_CONNECTION_REFUSED
TypeError: Cannot read property 'room' of undefined
at Socket.socket.on (C:\Users\Yaz\react projects\chat-app-3\server\index.js:38:16)
at Socket.emit (events.js:198:13)
at C:\Users\Yaz\react projects\chat-app-3\server\node_modules\socket.io\lib\socket.js:528:12
at process._tickCallback (internal/process/next_tick.js:61:11)
[nodemon] app crashed - waiting for file changes before starting...
I can’t quite see what is happening and why it would throw an error (new to sockets). the error is either in the front-end (Chat.js) or server (index.js):
Completed repo is below:
I would appreciate your help to see why is there an error so i can understand sockets more.
